The present invention relates to a fertilizer spreader, and relates to a configuration in which a plurality of types of fertilizer can be mixed and sprayed in a hopper.

As a background art, “the U-shaped bowl is equipped with a rotating shaft having a stirring blade in the U-shaped bowl to constitute a stirring unit that transfers the raw material while stirring in one direction. A set is provided adjacent to each other so as to be opposite to each other, and at the end of these transfer directions, a scraping material capable of moving the raw material is provided in an adjacent basket, and the raw material is continuously circulated and transferred. There is known a fertilizer spreader in which a discharge port is provided on the bottom surface on the end side in the direction, and a plurality of discharge ports are provided on the end side in the transfer direction with respect to the ridge length over a half length. (Patent Document 1)
JP 2003-235318 A

  According to a known technique, fertilizer is continuously circulated in a horizontal direction in a pair of adjacent U-shaped bowls and mixed, and a discharge port is provided on the bottom of each bowl, and the fertilizer is dropped from the discharge port. Because it spreads, it is spread with a maximum spreading width of approximately ridge width, which is disadvantageous when spreading over the entire area. For this reason, a fertilizer spreader that can efficiently mix fertilizer in a short time, can be spread in stripes or strips, and can also be used for spreading spread over a wide area is also available. To do.

  In order to solve the above-mentioned problems, a rotating shaft having stirring blades is provided in a U-shaped bowl to constitute a stirring unit that transfers fertilizer while stirring in one direction. A pair is installed adjacent to each other in the opposite direction, and a scraping material that can move the fertilizer is provided on the ridges adjacent to the ends in the transfer direction so that the fertilizer is continuously circulated. On the bottom surface of one side of the adjacent U-shaped bowl, a plurality of outlets are provided continuously to the width of the bowl in the transfer direction of the stirring unit, and fertilizer can be dropped from the outlet and sprayed. On the bottom face of the first spreading part and on the other side, there is a discharge opening in the middle part in the longitudinal direction, and below this discharge opening is mounted a rotating spraying plate that is horizontally rotatable with a circular plate with spraying vanes on the horizontal plane. And a second spraying section that allows the fertilizer that has fallen from the discharge port to be spread and sprayed by centrifugal force. When fertilizer application is to provide a manure spreaders which is characterized in that can be selected sprayed from the first spraying unit or the second spraying unit.

  In order to solve the above problems, in the invention according to claim 2 of the present invention, in the fertilizer spreader, in order to further increase the efficiency of continuous circulation of the fertilizer, on the start end side in the transfer direction of the stirring blades Provides a fertilizer spreader in which auxiliary stirring blades formed in a ribbon-like spiral are provided in two rows with the mounting phases of the stirring blade start end and the start end being shifted.

  In order to solve the above-mentioned problem, in the invention according to claim 3 of the present invention, in the fertilizer spreader, the fertilizer can be spread more efficiently and in a wide variety of spray patterns. A shutter plate for adjusting the amount of fertilizer falling is provided in close contact with the discharge port provided with a plurality of discharge ports on the bottom surface of the U-shaped bowl, and the drop port is provided for each discharge port of the shutter unit. Is provided with a flexible guide tube, and the distal end of the other end, which is the exit side of the guide tube, is located at a desired position of the lateral support member provided over the longitudinal direction of the U-shaped ridge. A fertilizer spreader configured to be able to hold a single guide tube or a plurality of guide tubes is provided.

  As mentioned above, the agitation part that moves while stirring in one direction to the U-shaped ridge is configured, and fertilizer can move to the adjacent ridge at the end of each transfer direction by combining the transfer directions in opposite directions Since a continuous scraping material is installed and stirred continuously, high-speed stirring is possible, and since spraying and spraying is performed directly from the bottom of the U-shaped bowl of the stirrer, the mixed fertilizer can be compressed and bridged smoothly. Can be mixed and sprayed. In addition, one side of a U-shaped ridge adjacent to a set can be spread on one side, or on the other side the fallen fertilizer can be spread and spread over a wider range than the ridge width with a rotating spreader, You can choose the spraying method that suits your crop and cultivation process.

  The invention according to claim 2 of the present invention is the start in the transfer direction of the agitation blade on the receiving side so that the fertilizer can easily move to the adjacent paddle by the scraping material provided at the end in the transfer direction of the agitation blade. A stirrer blade formed into a ribbon-like spiral on the end side is provided in two strips by shifting the mounting phase of the start end, and a smooth flow of fertilizer is formed by increasing the conveyance efficiency on the start end side on the receiving side, The efficiency of continuous fertilizer circulation can be improved.

  In the invention according to claim 3 of the present invention, a flexible guide tube is provided at the drop port provided in the shutter unit for adjusting the fertilizer fall amount of the discharge port, and the tip of the guide tube is provided. Is configured to be able to hold a single guide tube or a plurality of guide tubes at desired positions in the longitudinal direction of the U-shaped ridges. For example, the tip of the guide tube is attached to the planting ridge of the crop. Since it can be sprayed only on the planting ridges and the fertilizer can be sprayed in the form of stripes or stripes only on the necessary parts, the fertilizer is not sprayed wastefully.
